ABSTRACT
Objective:To design and implement a low-power and portable transcranial direct current stimulator controlled by mobile phones. Methods:The constant current stimulation circuit was realized by a field effect transistor, which could output stable and adjustable low-intensity direct current, and the impedance detection circuit and the over-current protection circuit increased the effectiveness and safety of the stimulator. The control and real-time detection of the stimulation circuit was realized through a microcontroller, and the parameters' settings of the stimulator and the display and preservation of the actual stimulus information were realized through the Android software on the smartphone. Results:The output current strength and accuracy, maximum load, as well as the timing, device connection, stimulus information collection and display all achieved the expected goals. Conclusion:The design realized the mobile control of the stimulator, with portability, low cost and low power consumption, providing a new solution for wider applications.
ABSTRACT
Objective: To research a intelligent mobile APP information platform is used to carry out remote diagnosis and treatment services for the patients with diabetes so as to improve the medical experience and treatment compliance of the patients with diabetes. Methods: The patient's physiological information data that were obtained from home wearable medical devices were collected through the Bluetooth technique by using wireless mobile network. And the APP system was used to carry out remote online multi-channel communication between doctor and patient, and was applied to establish relevant health records. Results: The control rate of blood sugar, blood pressure, blood lipid and other indicators of patients with diabetics have been increased from 33% to 70%, and the filing rate of health records of patients also has been increased from 29% to 85%. Conclusion: The application of multi-channel multimedia interconnect platform and the integration of health data of patients with diabetes can ensure patients to complete treatment in least process, and it can provided convenient communication in real time for doctor and patients. And it also can greatly enhance the efficiency for the management of diabetes, improve satisfaction of patient, reduce the risk of hypoglycemia and the complications of diabetes.
